What is the solution to the following equation?

х+ (-21) = 8

О А. x= 27

B. х = 29

с.   х = 13

D. х = 17

Option B

The solution to given equation is x = 29

Given that we have to find the solution of given equation

Given equation is x + (- 21 ) = 8

The value of the variable is found by adding, subtracting, multiplying or dividing both sides of the equation to simplify the equation and isolate the variable.

The goal is to have the variable on one side of the equation and numbers on the other.

From given equation,

x + ( -21) = 8

Let us first remove the brackets around -21

We know when we multiply a positive sign number with negative sign number, we get a negative sign number

x + 1( - 21 ) = 8

x - 21 = 8

Move -21 from L.H.S to R.H.S

x = 21 + 8

x = 29

Thus solution to given equation is x = 29 Thus Option B is correct
